So far, this barrel is awesome. Well made, great internal finish. When they mention micro-honed, they meant it. I've fired paint ranging from cheap field to expensive. And no breaks because of hte barrel.
I have read that it's heard to clean. I haven't had any issues with cleaning.
It's accurate as well. I have a GREAT grouping with this barrel. Better than my 14" Proto, which is ported while this barrel isn't.
And, the sound. It's loud. People know you're firing with it. And that ring when it fires from the muzzle break is very cool. First time I opened up with it people stopped to stare.
So, all in all this is an excellent barrel at an extremely good price.
Definitely get this if you want a G-36 barrel that runs great and is at a very reasonable cost. It's actually a steal for the quality.
